5K BE OLED version has A LOT more Screen Door Effect when compared to the the normal 5K+ , This is worrying?

@ mazi

That was not my question (only the half), you manipulated my quote :-).
Do both glasses have the same native resolution, or not?

My question:
“The native resolution of 5K+ and 5K BE is exact the same.”

@ meal_white

When did you test this? Can you please take pictures through the lenses?
You indirectly claim, you have compared that.

Are there generell comparings (pictures, reviews) for text at same resolution, between pentile and not pentile?

If not, these are all guesses.
See the very easy to read text on the Note 3 (Pentile, 1920x1080) and Note 4 (Pentile, 2560x1440).

Of course, the user is not so close, the picture is not inflated to a high FOV, but it shows how relative this statement is.

I wish I could turn off the light on the scanner.
Then maybe I could make a good picture of the smartphone display.
I could try to cover the light bar.

But I’ve already photographed a 65" with 3840x2160 pixel exact with a camcorder.
Possibly this also works with a 5.7" 2560x1440.

=> Does anyone know a good test picture?
With font and lines in different sizes. Down to very small font (down to illegibility on 2560x1440).
I would try to make pictures from the Note 4 display.
Someone else might try to take pictures of a 2560x1440 resolution LCD screen. Then we can compare.
My suggestion for scanners (with covered light bar), 600dpi.

Which screen size does the 5K BE have?
Also ~ 5,7 "? If not, no problem.
We can change the photos to the same screen size.

@ McEreno

Yes, there are lines between the pixels, but the native number of pixels is the same (or not?).
This is not text, that is not the identical picture. Not perfect to compare.
You can not compare the readability of text without text.
We need photos from the same test image through the lens.
With text that becomes so small that it is no longer legible on the LCD.
Then we can compare how legibility is at the same level (numbered text sizes).

I am aware that the 5K BE has a heavier SDE. But that’s no proof of poorer readability of text.
I own a 5.7"-Pentile OLED. We can make comparison images with the same test pattern.

And then a picture with filter. Maybe I get an anti-glare filter.
Except skai also has a 5.7 "OLED (Samsung AMOLED), and could make the pictures with its filter. Note 4, Note 5, Note 6, Note 7… AMOLED with 2560x1440.
Skai?

I can‘t and I never did talk about readability of a 5K BE. only 5K+ vs 8K.

if all testers say the readability is better on a 5K+ maybe we should trust them. doesn‘t mean you will have hard time reading on the 8K. search in swevivers channel, he has done videos about readability etc.

the thing that most are missing is the scaler. we are not just talking about rgb stripe vs pentile matrix. that particular scaler of the 8K is affecting readability aswell. so there is not much sense to compare mobile phone screens to get to a conclusion about a VR headset in this case.

pimax says the oled BE is not finished yet. thomas saw a big improvement in black smearing at CES compared to his first try at the berlin meetup but he mentioned SDE being worse than before - so pimax already changed the displays once and maybe will again.

pimaxes specsheet states the same exact resolution of 2560x1440 per eye on 5k+ and 5k BE. interesting fact: specsheet says BE has no brainwarp compatibility.

But this scaler provides a delay, a lag. Many feel that this is unacceptable.
The advantage of the 5K and 5K + is the direct control of the pixels. Without delay by scaling.

Quote from Reddit user “golflimalama2” about the odyssey+:

Completely disagree with this.
The anti-SDE doesn’t produce blurring. It actually makes text easier to read.
It’s like this is written by an angry OG user that hasn’t actually used the Plus. Caveat Emptor everyone.

And “conan48”:

Yes text, is more readable. I should have put that in positives. But, having pixels bleed over to get rid of SDE is definetely making the image “look” more soft, and no amount of super sampling helps. I could post pics of my odyssey plus if I have time. Luckily i can return it.

That’s the thing with first impression reviews. Nobody should be basing an order on something so flimsy.

I didn’t test it. I don’t have a headset yet and I won’t be getting a 5K BE.

I don’t need to test it, though.

The 5K BE clearly has more SDE and that will interfere will small text, especially when you consider that it’s using a PenTile pattern. Look at the 5K BE images (above, in this thread) and consider trying to read letters when ~1/3 of the subpixels are replaced with black voids: https://community.openmr.ai/t/5k-be-oled-version-has-a-lot-more-screen-door-effect-when-compared-to-the-the-normal-5k-this-is-worrying/13000/60?u=neal_white_iii

Apart from the sde,
i would like to know how the clarity/resolution compares to the 5k+

The OLED version has the same resolution as the 5K+. HOWEVER, it uses a PenTile pixel arrangement, which means that there are fewer sub-pixels, compared to the 5K+ which has full RGB sub-pixels for every pixel.

More details: PenTile matrix family - Wikipedia

Every once in while I see comments on how dull the colours look on the 5k+ compared to the Vive . I am glad I only have a Rift so hopefully difference isn’t so obvious .

70

That’s not good news because now that I have had my 5K+ for a few weeks the honeymoon is over so to speak and I can’t believe the screen door effect. Yes, if you don’t look for it then you don’t notice it. But…it’s still there and quite obvious…ha I can’t unsee it now.

Yes but to be honest it’s still the best SDE except for the Samsung od+ and maybe for some the 8k+.

Oled Pentile is the way to go, with HP reverb resolution per eye with PSVR’s and Odyssey’s Anti SDE, with around Pimax’s 130 FOV!

Produce a square or vertically bigger panel around 2k per eye with anti SDE with 130ish FOV, either old proven style of Oculus and Quest headstrap and headphones, or do it like PSVR’s or WMR, or new Rift S but with integrated Mantis headphones (while keeping everything as light as possible though) than you will finish the line of the perfect gen1 VR headset…

I just hope, Samsung would do this or Oculus Rift Pro in a year!

73

Yes but trying to rationalize to myself why I didnt notice it as much on the Rift…the mind can play funny games on you.

74

Had a chance to try to XR/BE edition about a month ago.
Did not spend much time on it to be completely honest, just Pimax home Moon background but did spend 30 mins with a 5k+ just before and have to say the first thing i was looking for after watching MRTV’s video is the SDE, wanted to compare it with my Rift and 5k+.
Truth is that i did see an improvement over the Rift, but its was still very present and jumped to my eyes straight away, colours were a bit warmer but too much for my taste.
Having said that, i don’t think they should have offered the XR/BE for costumer to purchase.

This reminds me of the Vedic / Buddhist concept, “You are the space between your thoughts”

It’s the SDE of philosophy :joy:

Didn’t Oculus forsake OLED panels in their Rift S exactly because space between pixels is larger than on LCD panels? (different matrix type).

Anyway, as long as they don’t make a blurry mess like with the PSVR anti-sde solution …
